[Pansophy] SNs for L2RB cavities

[Mike Dickey]

Hi John,

Will the "to be delivered" cavities be NEW or REPORPOSED & REPROCESSED cavities.  I am concerned about traceability for datamining inspection and processing data if the need arises.  The L2RB redesignation will hide the cavities origin causing a potential loss critical data.

Subject: SNs for L2RB cavities

Hi Mike,

I've caught a slight discrepancy in the SN numbers for the new L2RB cavities in the system. Overall, I suggest replacing the "HE" in "HE-CAVRXXX" with "L2RB".
However, we need to distinguish between former L2 and L2HE (production) cavities. The way this is done is that the L2 cavities have a leading 0 while the L2HE cavities have an R.

Currently, this mostly affects the two reuse cavities from L2-J11. Those are L2RB-CAV0167 and L2RB-CAV0140. I want to make sure to avoid any confusion with HE cavities CAVR140 and CAVR167.
Beyond those, we either got in house or are expecting:

  *   L2RB-CAVR023 (to be delivered)
  *   L2RB-CAVR036 (to be delivered)
  *   L2RB-CAVR043
  *   L2RB-CAVR049
  *   L2RB-CAVR094
  *   L2RB-CAVR106
  *   L2RB-CAVR113
  *   L2RB-CAVR132 (to be delivered)
  *   L2RB-CAVR135
  *   L2RB-CAVR138 (to be delivered)
  *   L2RB-CAVR147 (to be delivered)
  *   L2RB-CAVR198 (to be delivered)
  *   L2RB-CAVR200 (to be delivered)

As of now, the L2RB traveler SN selection lists those all with a leading 0. We should correct this to avoid confusion with old L2 cavities. Would it be possible for you and the @pansophy<mailto:pansophy at jlab.org> team to fix that?

Best,
John V
